Vertical Solder Spool holder v2_WireGuideRemix

Retro frog’s vertical bearing design is really THE best, it's really stable during unwinding and have a minimal look and filament usage. However I have improved on things that I think is crucial to become perfect: 1) reduced the footprint to its bare minimum 2) added a wire guide. 3) Modified the pin to accept M3 heatset insert, but you could also use the original pin from his original model if you prefer self-tapping.

Parts:

-8x22x7 mm bearing (standard skateboard wheel bearing)

-M3 headset insert (optional and any size)

-M3 screw (around 15mm is ok)

Reduced footprint and added a wire guide, and modified the pin to accept M3 heatset insert (Can also use the pin from original model)
